GHK-Cu is susceptible to hydrolysis and oxidation
These usually resolve without intervention within 48 hours
Most of the promising research comes from a single lab whose lead scientist holds patents on the compound
The benzyl alcohol preservative inhibits bacterial growth Sterile water has a shorter window If reconstituted with plain sterile water (no preservative), use within 48 hours or freeze in single-use aliquots Avoid freeze-thaw cycles Repeatedly freezing and thawing a reconstituted peptide solution causes degradation
